Application filed September 2, 1909.

To all whom it may concern:

Be it known that I, THOMAS E. SHANA- HAN, of Manlius, in the county of Onondaga and State of New York, have invented a certain new and useful Trolley-Pole Retriever, of which the following is a specification.

My invention has for its object the production of a trolley-pole retriever which is particularly simple in construction and durable and eiiicient in use; and to this end it consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

Figure 1 is a longitudinal sectional view, partly in elevation, of my trolley-pole retriever. Fig. 2 is a sectional view on a smaller scale, on line A A, Fig. 1. Fig. 3 is a face view of the inner wall of the support or case, and the shifter carried thereby. Fig. 4 is an end view of the reel and the movable locking member for the spring.

This trolley-pole retriever comprises gen erally a support, a reel for the trolley-pole rope, a spring for turning the reel to wind the rope thereon, the spring being normally under tension and rotatable with the reel, and means for normally holding the spring under tension and from turning the reel, said means being shiftable out of its normal position to connect the spring to the support and release the spring to turn the wheel.

The support 1 which may be of any desirable form, size and construction, is here shown as a hollow shell comprising an inner wall or base 2, and a cap 3 detachably se cured to the wall or base 2 by any suitable means, as screws 4. The support 1 is formed with an opening 5, Fig. 2, for the passage of the trolley-pole rope 6, and the wall or base 2 of the support isprovided with any desirable means adapted to be attached to the dashboard or other suitable part of the car.

As best seen in Fig. 1, the reel 7 is loosely mounted on a shaft 8 journaled in the support 1, as hereinafter described, said reel be ing formed with a peripheral wall, a web 9 between the opposite ends of the reel, and a hub 10 encircling the shaft 8 and projecting from one side of the web toward the inner wall or base 2, the peripheral wall Specification of Letters Patent.

having the trolley-pole rope 6 partly Wound thereon; and the web 9, the hub 10 and the opposing portion of the peripheral walh forming an annular chamber within the reel. The spring 11 for winding the trolley-pole rope 6 upon the reel 7 is arranged in said annular chamber within the reel and is coiled around the hub 10, the inner end of the spring 11 being suitably fixed, as by a rivet 12, to said hub. The outer end of the spring 11 is suitably fixed, as by a rivet 13, to a holder or barrel 1 1 comprising a cylindrical flange, and a disk-shaped wall 15, the cylindrical flange loosely fitting the portion of the peripheral wall of the reel 7 surrounding the hub 10, and the wall 15 loosely encircling the shaft 8 and having its outer face substantially coincident with the contiguous end face of the reel 7, and its inner face provided with a hub 16 abutting against the hub 10.

The means for normally holding the spring under tension comprises a locking member 17, movable about the axis of the reel and also lengthwise of such axis and the shaft 8, and here shown as a disk loosely mounted on the shaft 8 adjacent to the end wall 15 of the spring holder and the contiguous end face of the reel 7. This member 17 is slidably interlocked with the spring holder 14, being here shown as formed with openings 18 which receive shoulders 19 projecting from the opposing surface of the holder. Said member 17 is also provided with notches extending inwardly from its peripheral edge and forming shoulders 20 for coacting alternately with shoulders 21 and 22 provided upon opposing faces of the reel 7, and the inner wall or base 2 of the support 1, the shoulders 20 being normally engaged with the shoulders 21 and being movable out of engagement with the shoulders 21 into engagement with the shoulders 22 when the member 17 is shifted to the right. The shoulders 19 are of greater length than the shoulders 21 or 22, so that said member 17 is engaged with the shoulders 19 when the shoulders 20 are engaged either with the shoulders 21 or the shoulders 22; and the shoulders 21 and 22 are preferably provided with inclined or cam faces coacting with walls of the notches forming the shoulders 20 for facilitating shifting of the member 17. When the member 17 is in its position assumed in Fig. 1

with its shoulders 20 engaged with the shoulders 21, the spring 11 rotates with the reel 7 and is normally held under tension without effecting any movement of the reel, but when the member 17 has been moved axially to the right disengaging its shoulders 20 from the shoulders 21 and engaging the shoulders 20 and 22, the member 17 holds the outer end of the coiled spring 11 from movement with the reel, and thereupon the spring 11 operates to turn the reel and wind the trolleypole rope upon the peripheral wall of the reel.

As shown in Fig. 1, the locking member 17 is moved lengthwise of the shaft 8 by a shifter 23 arranged in axial alinement with the shaft 8 and journaled in the wall or base 2 and movable endwise relatively to said wall or base. This shifter 23 is formed with a socket 2% extending inwardly from one end thereof and receiving the contiguous end of the shaft 8 which terminates short of the bottom 25 of the socket 24L and has a non-circular extremity 26 fitting a correspondingly-shaped portion of the socket 2a. The shifter 23 is provided with segmental bearing faces 27 arranged diametrically opposite to each other, and with segmental spaces or cutouts between the opposing ends of the faces 27. Cams 28 arranged on op posite sides of the axis of the shaft 8 and fixed to the wall or base 2 are normally engaged with the faces 27 by a spring 29 interposed between the bottom 25 of the socket 2d of the shifter and the contiguous end of the shaft 8. When the free end of the trolley-pole flies upwardly owing to the disengagement of the trolley from the wire, the shaft 8 is partially rotated with the reel 7, by connections presently described, and upon such rotation of the shaft the shifter r0- tates therewith carrying the faces 27 from their normal position in engagement with the high points of the cams 28 to a position opposite to the low points thereof. During this partial rotation of the shifter 23, the spring 29 slides the shifter axially and the axial movement of the shifter moves the locking member 17 to the right, Fig. 1, and disengages the shoulders 20 of the member 17 from the shoulders 21 of the reel 7 and engages said shoulders 20 with the shoulders 22 of the wall or base 2. Upon the reverse partial rotation of the shaft 8 and the shifter 23 the faces 27 ride up the inclined surfaces of the cams 28, thus sliding the shifter to the left against the action of the spring 29, and moving the locking member 17 to the left and disengaging its shoulders 20 from the shoulders 22 and engaging said shoulders 20 with the shoulders 21 of the reel. It is thus apparent that the engagementof the shoulders 20 of the locking member 17 with the shoulders 22 of the wall or base 2 is effected by the spring 29 thereby avoiding liability of injury to said shoulders 20 and 22 when being engaged.

Preferably, the shifter 23 is connected to the locking member 17 by a lost motion, the end of the socket 2 f of the shifter nearest the locking member 17, being here shown as provided with an enlargement 30 which receives a hub 31 provided on the opposing side of the member 17, the inner face 32 of the enlargement 30 being spaced apart from the end face of the hub 31, and the outer end of the enlargement 30 being provided with inwardly extending shoulders which enter a circumferential groove 3% in the hub 31, this groove being of greater width than the shoulders 33. A spring 35 is arranged in the enlargement 30 around the shaft 8 and between the inner face of the enlargement and the opposing end face of the hub 31, the spring serving to transmit motion from the shifter for moving the member 17 to the left and thereby yieldingly forcing the shoulders 20 of the locking member into engagement with the shoulders 21 of the reel 7, and the lost motion or space bet-ween the shoulders 33 and the opposite wall of the groove 34 permitting the shifter 23 to move relatively to the locking member a limited distance.

The spring 35 constitutes yielding means for normally holding the locking member 17 in engagementwith the reel 7, and the spring 29 acting on the shifter constitutes additional yielding means for forcing the locking member 17 out of engagement with the reel and into engagement with the su iport 2, the spring 29 being normally restrained from acting by the cams 28 coacting with the shifter. The power transmitting means between the disk 38 and the locking member 17 comprises a shaft 8, spring 29 and shifter 23.

The means for connecting the reel 7 to the shaft 8 when the trolley carried by the trolley-pole is disengaged from the trolley wire preferably consists of dogs 38 pivoted intermediate of their ends at 37 to the outer or left end face of the reel 7, corresponding ends of the dogs 36 being adapted to engage a disk 38 fixed to the shaft 8 and their other ends being weighted and connected to springs 39 carried by the reel, these springs 39 normally holding the dogs out of engagement with the disk 38. The centrifugal force, due to the rapid rotation of the reel 7 by the upward impulse of the free end of the trolley-pole when the trolley is disengaged from the wire, throws the weighted ends of the dogs 36 outwardly and causes the opposite ends of said dogs to engage the disk 38, whereupon the reel 7, the disk 38 and the shaft 8 revolve together.

The disk 38 is shown as formed separal Cit 3 of the support 1 and as provided with hubs 41, 42 extending from opposite sides of the disk and fitting the shaft 8, the outer hub 41 being journaled in a bearing 43 in the cap 3 of the support 1 and the inner hub 42 abutting against the web 9 of the reel 7, and being fixed to the shaft 8 by a pin 44. A coiled spring 45 surrounds the inner hub 42 of the disk 38 and its opposite ends are respectively secured to said hub 42 and to the reel 7, this spring serving to rotate the reel 7 to take up the slack in the trolley-pole rope, due to the different levels of the trolley-wire.

My trolley-pole retriever is provided with a hand-lever 46 which is suitably fixed to the shaft 8, and is here shown as encircling the extremity of the outer hub 41 of the disk 38 and as held in position on such extremity by a plate 47 and a screw 48 passed through the plate 47 into the end of the hub 41. The hand lever 46 provides means for en abling the operator to rotate the shaft 8 to move the locking member 17 into engagement with the reel 7, and thus reset the shifter 23 and the locking member 17 in their normal position after the trolley-pole has been retrieved.

In operation the parts are normally in the position shown in Fig. 1, and when the trolley leaves the wire, it springs upwardly rotating the reel 7 as the trolley rope unwinds. During such rotation the centrifugal pawls 36 are thrown into engagement with the ratchet teeth of the disk 38 against the action of their springs 39 and the disk 38 partially rotated thereby until the cams 27 have been moved over the face of the cams 28 into such position that the spring 29 can move the member 23 outwardly axially positioning the cams 27 between the cams :28. The rotary movement of the disk 38 is transmitted to the shifter 23 through the shaft 8. The outward movement of the shifter 23 by the sprin 29 shifts the locking member 17 from its position shown in Fig. 1 in which it is engaged with the lugs 21 of the reel, into engagement with the lugs 22 of the support or case 1, thus anchoring one end of the spring to the support, the other end of the spring being connected to the reel. The reel will hence be rotated by the spring 11 in the opposite direction to that in which it is rotated by the trolley rope, thus moving the pawls 36 in a retrograde direction so that their springs 39 can return them to their normal position. During the movement of the reel by the spring 11, the disk 38 and shaft 8 and member 23 remain stationary. After the trolley has been retrieved, the spring 11 is restored to its original tension by pulling on the trolley rope and unwinding the same from the reel sufliciently to permit the trolley to touch the wire and have the usual amount of slack. The shifter 23 and parts operated thereby may then be reset in their initial position by means of the lever 46.
